Connectronomy analysis methods write up
A diffusion spectrum imaging scheme was used, and a total of 128 diffusion sampling were acquired.
The maximum b-value was 4990 s/mm². The in-plane resolution was 1.8 mm. The slice thickness was
1.8 mm. The accuracy of b-table orientation was examined by comparing fiber orientations with those of a population-averaged template (Yeh et al. Neuroimage, 2018). The b-table was flipped by The diffusion data were reconstructed in the MNI space using q-space diffeomorphic reconstruction (Yeh et al., Neuroimage, 58(1):91-9, 2011) to obtain the spin distribution function (Yeh et al., IEEE TMI, ;29(9):1626-35, 2010). A diffusion sampling length ratio of 1.25 was used. The output resolution in diffeomorphic reconstruction was 1.8 mm isotropic. The tensor metrics were calculated using DWI with b-value lower than 1750 s/mm². The quantitative anisotropy was extracted as the local connectome fingerprint (LCF, Yeh et al. PLoS Comput Biol 12(11): e1005203) and used in the connectometry analysis.


Diffusion MRI connectometry (Yeh et al. NeuroImage 125 (2016): 162-171) was used to derive the correlational tractography that has QA, MD, AD, and RD correlated with Maze Accuracy and Loop variables. A nonparametric Spearman partial correlation was used to derive the correlation, and the effect of sex, age_scan_years, and repo_status was removed using a multiple regression model. The total number of subjects varied on analysis (See Analyses and Final sample sizes above). A T-score threshold of 2.5 was assigned and tracked using a deterministic fiber tracking algorithm (Yeh et al. PLoS ONE 8(11): e80713, 2013) to obtain correlational tractography. A seeding region was placed at whole brain (39,49,29) .

The tracks were filtered by topology-informed pruning (Yeh et al. Neurotherapeutics, 16(1), 52-58, 2019) with 4 iteration(s). A length threshold of 25 voxel distance was used to select tracks. To estimate the false discovery rate, a total of 4000 randomized permutations were applied to the group label to obtain the null distribution of the track length.







Results

Maze Accuracy



Summary

A total of 82 diffusion MRI scans were included in the connectometry database. For the connectometry analysis, age, sex and repo status were listed as covariates. All subjects displayed Positive Correlations and negative correlations between tracts with QA and Maze accuracy.Tracts in the fornix with MD and RD displayed Positive Correlations relationships with Maze accuracy. AD displayed a negative relationship between tracts in the fornix and maze accuracy. All together the results suggest that increased diffusion (Md and RD) are associated with increased performance in scores in midlife participants and these associations are found in regions associated with spatial navigation. When split by sex, Men displayed a negative association between maze performance and a majority of tracts in the corpus callosum with QA. For AD, RD, and MD, men displayed significant Positive correlations relationships between performance. Altogether it suggests that better maze accuracy is associated with increased diffusion in midlife men. Women displayed the opposite, tracts in the fornix with QA were positively associated with performance while tracts in the fornix, cingulum, and cerebellum and with AD,RD, and MD were negatively associated with performance. Suggesting that more specific diffusion is associated with better maze accuracy. Next, Menopause stages were analyzed separately. Pre menopausal women displayed both positive correlations and negative correlations with QA while tracts with AD,RD and MD displayed negative relationships. Peri menopausal women displayed Positive Correlations associations in tracts with QA, MD, RD, and AD and performance. This suggests that in peri menopasual women, maze accuracy is associated with increased diffusion in tracts on the fornix, cerebellum, and cingulum. Post menopausal women displayed both positive correlations and negative associations between acc and QA. Post menopausal women displayed Positive Correlations and negative associations with QA< MD, RD, and AD and maze accuracy. A majority of tracts in the fornix with AD,MD, and RD were positively associated with maze accuracy

QA

Summary of results

There were both Positive Correlations and negative correlations between QA and maze performance when all subjects were included in the analysis. When men were analyzed separately, men displayed more negatively associated correlations between QA and maze performance. Women displayed tracts with predominantly Positive Correlations correlations between QA and performance. When split by menopause stagge, Pre and post displayed both Positive Correlations and negative correlations while peri displayed only Positive Correlations correlations with performance.

MD

Summary of results

DSI was run on all subjects, with sex and age listed as covariates. There were Positive Correlations correlations between MD values in the Fornix (L&R) and performance. Using a sex stratified apporoach we viewed the relationship between white matter and performance in men and women separately. Men, displayed a majortiy of Positive Correlations correlations between tracts with MD and accuracy. Specifically in regions associated with navigation such as the fornix (L & R). Women, displayed a majortiy of negative correlations between tracts with MD and accuracy. Specifically in regions associated with navigation such as the fornix (L & R), and cerebelllum. We then investigated the relationship of white matter and performance when splitting by menopause stage. Pre menopause women displayed a majortiy of negative correlations between tracts with MD and accuracy in the fornix(L&R) and corpus callosum. Peri menopause women displayed a majority of Positive Correlations correlations between tracts with MD and accuracy in the fornix(L&R) cerebellum and cingulum. Post Menopause displayed both Positive Correlations and negative relationships between MD and performance. The majority of tracts with Positive Correlations correlations were in the fornix, while a majority of the negative correlations were found in tracts in the parietal cortex and cerebellum.

All subjects analyzed, tracts in the fornix were positively associated with acc. In Men, tracts in the fornix were positvely associated with acc. Women showed tracts in the fornix were negatively associated with acc. Pre menopausal women showed a similar findings to women with negative correlations in tracts in the fornix. Peri menopasual women showed results similar to men, with tracts in the fornix positively associated. Post menopausal women displayed Positive Correlations and negative associations with a majority of Positive Correlations tracts located in the fornix and negative tracts in the cerebellum.

Maze Path Efficiency

We would expect that lower QA values would correspond to higher PE scores. higher PE scores indicate worse efficiency

  • All subjects
    • Negative correlations in corpus callosum and cingulum. Meaning that those with higher QA values had better efficiency scores ( correct trial only also had negatve only.)
    • MD exhibited negative correlations suggesting lower MD corresponded to higher scores. Lower diffusivity corresponded to worse efficincy ( same for correct trials only)
    • AD had tracts but they were less than 10. nothing significant for correct trials
    • RD was negative only correlations ( Same with corect trials only : Fornix only)
  • Men
    • QA had tracts that were positively and negatively correlated
    • MD was negatively correlated with PE scores. ( Correct only had pos and negative)
    • AD displayed negative correlations suggesting more specific diffusivity corresponded to better efficicency ( correct trials had pos and neg)
    • RD had negative correlations
  • Women
    • QA displayed pos and negative correlations but mostly negative ( same for correct trials)
    • MD displayed pos and negative correlations but mostly negative corrs. (correct only did not have any correlations
    • AD displayed pos and negative correlations but mostly negative corrs (correct only did not have any correlations) -RD displayed pos and negative correlations but mostly negative corrs (correct showed same po/neg)
